I suspect many people would dismiss this article simply because it appears in the Mail Online, but that would be a shame, because it's a piece that's worthy of note. Not only is it a serious article on the subject of 9/11, appearing in a mainstream news outlet, it actually does quite a good job of presenting some of the reasons (including Building 7) why many thinking people continue to question the standard account of that day, and it does so without discounting all suggestion of conspiracy.
